The Clean Power Plan is a federal rule aimed at cleaning up electricity's carbon footprint. It's America's most ambitious effort yet to fight climate change. But how big of a deal is it?

Well, American energy use is a whopper — 98 quadrillion BTUs last year. It's a number so big, what does it even mean? Well, it's enough to send a Saturn V rocket to the moon every 26 seconds for a whole year.

As America plans to move away from coal-fired power plants to renewable energy, the country plans to build more commercial wind farms.

But the country's first commercial wind farms are nearing retirement, and there are few requirements to take them down. Inside Energy's Leigh Paterson looks at who is responsible for taking down the giant turbines.

For the poorest among us, paying every bill can be a struggle, including the power bill.

Solar power hasn’t really been a go-to option for those at the bottom, but that’s starting to change. Colorado’s largest utility — Xcel energy — recently announced an expansion of a program to provide solar energy to low-income residents. It’s part of a proposed settlement agreement with the state’s public utility commission.

Our electric grid sends power from power plants to our houses via thousands of miles of wires. Why can't we send that power without the wires?

Well, we almost did. To answer this question, Inside Energy — an Innovation Trail partner — went back to an inventor named Nikola Tesla, who experimented with this very idea back in the 1890s. Learn more in the video:

You may not notice it at first, but atop the roof of the wine press building at Lakewood Vineyards is something that marked the beginning of change in the region.

The 47-kilowatt solar energy system has been invaluable to the Watkins Glen, New York winery, according to president and winemaker Chris Stamp. If he has his way, workers will install more panels once the building’s expansion is complete this summer.

Lakewood started harnessing the power of the sun four years ago, a move Stamp said put them “way ahead of the curve” compared to other Finger Lakes wineries.
